The drive in the 8940 is no doubt NVMe, which the notebook you have will not take -- it will only take SATA M.2 drives.

You can clone the existing drive to a new NVMe drive for the desktop system, but the only way you can use the existing SSD with that notebook is by mounting it in an external case for use as a USB drive.

@ejn63​ that's how I tried to do it a year or 2 ago with an external case. So chances are I bought the wrong type of SSD? Going through my Amazon history it says I ordered and returned a Samsung 970 EVO 1 TB NVM.e in March 2022 which you say wouldn't work. So you're saying I have to find a SATA M.2 drive for the laptop? Physically speaking, the drive I had and the one on the laptop looked identical.

The 970 Evo will not work in the Inspiron 7378.  

SATA and NVMe drives are very simliar in appearance but completely different electrically.  If you want to upgrade the notebook, you need a SATA M.2 drive.  They are still available.

Samsung and others also still make them.

@ejn63​ OK thank you for the insight. I'll look into those with next week's check. This weekend I'll open up the PC to confirm that it has an NVMe drive as it should. There was something I came across regarding Windows UEFI booting (?) if a drive > 2TB. Is that gonna be an issue since I'm after a 4 TB?

Successfully cloned and upgraded the 8940 with a Samsung 990 Pro (and doubled the RAM) over the weekend. Currently monitoring its paces before wiping the original 2 TB Samsung SSD.

Confident to try to upgrade the laptop in a few weeks when funds replenish.
